- Thermal Conductivity
- Ceramics such as silicon carbide (SiC) have high thermal conductivity. Because of the high surface area of Duocel® foam, heat transfer to/from fluids flowing through the foam is greatly accelerated.
- Duocel® silicon carbide foam is also ideal for use with phase change materials (PCM) because of the large amount of surface area, which increases coupling to PCM.
- Electrical Conductivity
Duocel® ceramic foam can be used in electrochemical processes that require low electrical and fluid flow resistance. This is in stark contrast to most ceramics, which do not conduct electricity. Duocel® supplements its strength in this type of application with its increased ability to withstand extreme temperatures.

Strength
For Duocel® ceramic foams weight it is exceptionally strong. This strength is also extended to high temperatures. On top of that SiC is is very scratch resists at 9 Mohs.
Stability
Duocel® ceramic foam is structurally stable at elevated temperatures. It has a very low coefficient of thermal expansion and is resistant to thermal shock.Corrosion resistance
Duocel® ceramic foam resists oxidation up to 3002F. Ceramic also has high resistance to acid corrosion. It has a hardness that reduces the mechanical wear of the surface of the foam.
